Question

Diagonals of a rhombus are 20 cm and 21 cm respectively, then find the side of rhom-
bus and its perimeter.
hey students

sorry I am not able to answer your question ​

Answer 1

Answer:

1/2*D1*D2

1/2*20*21

210cm2 is area

Answer 2

Step-by-step explanation:

all sides on a rhombus are equal

take d1 = 10+10

and d2 = 10.5+10.5

in a right triangle base = 10 and height = 10.5

by pythogoras theorem a^2=10^2+10.5^2

a^2=210.25

a=10.5

perimeter=4a

=4×10.5

=42.0

thus side = 10.5

perimeter=42.0

hope you got it
